Testing the Telephone's Lights and Display
1. With the telephone idle (on-hook), press and release the Mute button, then press the following
numbers on the dialpad: 8 3 7 8 # (which stands for TEST).
•
The display should indicate the self-test has started. If the test is successful, the message
"Self test Passed #=end" displays; if the test is not successful, the message "Self test
Failed #=end" displays instead.
2. Press # to return to the Phone screen.
•
If nothing appears on the display and the phone is receiving power, your phone may need
to be replaced. Contact your System Administrator for assistance or additional
troubleshooting information.
